CHAIN BRACELET.

SPECIFICATION forming part of Letters Patent No. 315,525, dated April 14, 1885.

. Application filed October 9, 1884. (No model.)

To all whom it may concern:

Be it known that I, WILLIA I. MAooMBER, of Providence, in the State of Ithode Island, have invented an Improvement in Chain Bracelets, of which the following is a specification.

The nature of my invention consists in an improved box-clasp for a chain bracelet, by means of which the bracelet is made adj ustable to the wrist of the wearer, as hereinafter set forth.

Figure 1 is a top view of a chain bracelet, showing the bracelet in an unclasped condition, wit-ha portion of thehinged cover broken away, in order to more fully show the form of the locking-springs. Fig.2 is a partial section of the bracelet taken in the line 00 x of Fig. 1. Fig. 3 is an enlarged section showing the several parts in their locked condition. Fig. 4 is a transverse section taken in the line 00 w of Fig. 3. I

In the accompanying drawings, A is the ordinary roller-chain secured at its end a to the rear of the ornamental box 13, which is provided with a cover, I), hinged to the box at the point 0. At the under side of the coverb are secured the downwardly-projecting hooks d d,which,when the cover his closed upon the box, serve to catch under the springs C G,and thus hold the cover firmly upon the box; and the cover may be thrown back, as shown in Figs. 1 and 2, by first forcing the springs O C inward, by means of pressure upon the ends of the laterally-projecting studs e e, which project through suitable openings, f, made in the side of the box. The forward end of the box is cut away and provided with a catchpiece, 9, having upright pins or teeth h-h h, adapted to enter the spaces between the roller-links of the chain, as shown in section in Fig. 3.

The bracelet being first placed upon the wrist of the wearer, the free end j of the chain is brought forward to the proper distance within the box 13 and caught over the pins h,

I which enter the spaces between the links.

The

cover bis then to be broughtto its closed po-- sition, the thinned end of the hooks d enter ing the space 70, formed between the springs O and the inner sides of the box, and when the cover is completely closed upon the box the v hooks 11 will catch under the lower edge of the springs, as shown in Fig. 4, in which po-, sition the cover will be firmly held, so as to lock the chain upon the pins h until the hooks? are released from the springs by the inward movement of the projecting studs e,which form a lateral continuation of the free end of the spring.

I am aware thatahinged fastening for bracelet chains is shown and described in Patent of the United States No. 283,333, having a series of teeth in thebase, and a cover-platepro- I.

vided with a spring-catch device adapted to engage the base-plate and hold the teeth thereof in engagement with the chain.

I therefore make no general claim to such a fastening device for bracelets, but only to the improved construction and arrangement of the springs In a bracelet, the combination of the chain A, the box B, secured to one end of the chain and provided at its forward end with the catchpiece g, having upright pins 71., adapted to enter the spaces between the links of the chain, the hinged cover 12, closing downward in the direction of the chain, and providedat its under side with the opposite hooks, d d, the oppositely-arranged springs O C, provided with a projecting stud, e, and adapted for locking engagement with the hooks d d,which are held between the springs O G and the sides of the I box, substantially as described.

WILLIAM I. MACOMBER.
